[0002] Connector
[0004] Field of the invention
[0006] This invention relates to connectors used to establish an electrical connection, and in particular to connectors used in telecommunications and electrical networks.
[0008] Background of the invention
[0010] As the demand for higher signal and data performance continues to increase over broadband cable / CATV networks, service providers are striving to increase the bandwidth of their networks and increase the maximum frequencies of functioning.
[0012] The junction boxes used in these networks to split / combine RF signals require low signal loss cable terminations that can pass RF signals and also high AC / DC current to power line equipment. Traditionally, this is accomplished by bolting onto a conductive cable core within the junction box.
[0014] The impedance of the junction box has to be matched to that of the network to allow efficient signal transmission. As the frequency of the operating signal increases, the impedance matching of the cable terminations becomes more critical, as the attenuation of the signal due to impedance mismatch tends to increase with frequency. Screw clamp connectors are poorly matched to the impedance of the cable network, but are suitable at frequencies up to approximately 1 GHz, although at frequencies above these they begin to cause significant signal attenuation due to mismatch of the signal. impedance.
[0016] Summary of the invention
[0018] In accordance with the present invention, there is provided a connector comprising an electrically conductive element fixed in position within a rotatable insulating body, the electrically conductive element comprising at least one connecting channel, and a deflection element connected to the insulating body, wherein the insulating body is formed by at least one conical guide channel in which an insertion axis is located and the insulating body can rotate from a first deflected position, in which the at at least one conical guide channel is offset from the at least one connection channel, to a second offset position in which the at least one connection channel is aligned with the insertion axis, thus allowing the insertion of an elongated conductor, such as a conductive pin, in the electrically conductive element while the deflection element resists removal of the pin from the electrically conductive element. Therefore, a conductive plug, for example, forming the central core of a coaxial cable, can be inserted along the insertion axis to establish an electrical connection with the electrically conductive element. When such a connector is arranged within a distribution outlet or junction box, an electrical connection can be established between an external trunk cable, such as a coaxial cable, and a printed circuit board within the outlet or from the box.
[0020] Preferably, the insulating body is rotatable by inserting a conductive pin into the at least one conical guide channel. During use, when a conductive pin is inserted along the insertion axis, the insulating body is rotated against the biasing force exerted by the biasing element, rotating from the first biased position to the second biased position and aligning the insertion shaft and the connecting channel. This allows the conductive plug to enter the connecting channel and thus establish electrical contact with the electrically conductive element, and thus establish electrical contact with a printed circuit board connected to the electrically conductive element.
[0022] The electrically conductive element is preferably elongated and can usually be connected to a printed circuit board.
[0024] The electrically conductive element may comprise two connecting channels that intersect to form four orthogonally spaced inputs, suitable for receiving an externally inserted conductive plug.
[0026] The biasing element is preferably a spring and more preferably a torsion spring.
[0028] The deflection element may further comprise fixation elements, usually in the form of openings formed in the deflection element with fixation screws or pins, so that the deflection element can be fixed in position, for example inside the connector housing, the socket housing or the junction box housing.
[0030] The insulating body can be formed by one or more seat portions in which the deflection element can be located.
[0032] The body may be formed by one or more additional guide channels to receive an externally insertable conductive plug, such as for example a plug connected to the center conductor of a coaxial cable.
[0034] The insulating body can be formed by at least two arms arranged orthogonally. Generally, distribution taps and junction boxes have one or more entrances arranged orthogonally to connect to the main cables, so having at least two arms arranged orthogonally ensures that connection can be made to either of the entrances.
[0036] The insulating body can be formed of two separate pieces that can be connected to each other to secure the electrically conductive element, preferably with the electrically conducting element deflected to the first position by the deflection element acting on the insulating body.
[0038] The connector may further comprise an element fixed relative to the biasing element to define an insertion channel aligned with the insertion axis, for example an insulated bushing element. An element of this type can be incorporated into the connector or used in combination with it, for example when the connector is part of a distribution socket.
[0040] The invention will now be described, by way of example, with reference to the accompanying drawings in which:
[0041] Figures 1 (a) and 1 (b) show a perspective view and a sectional view, respectively, of a distribution outlet of the prior art;

[0043] Figure 3 (a) shows the connector before its placement in a socket, Figure 3 (b) showing an exploded view of the parts that make up the connector; and
[0044] Figures 4-6 show cuts through a portion of the socket from below while inserting a conductive pin to illustrate the operation of the connector.
[0046] Description
[0048] Figures 1 (a) and 1 (b) show a state-of-the-art distribution outlet 10 used in broadband and CATV networks. The socket 10 is connected at the main ports 12 to a main coaxial cable 14 via main connectors 16. The cable 14 carries bi-directional signals over the network and users connected to the ports 18 can send and receive signals. If desired, trunk cable 14 can be connected to outlet 10 using alternate trunk ports 20. An enlarged view of the socket housing 22 is shown in Figure 1 (b), where a clamping screw 24 at right angles to the main connector 16 is used to clamp a pin 26 of the main input / output conductor to the connector 28 on the printed circuit board (PCB) to establish an electrical connection to the components on PCB 30. Above 1GHz frequencies, the large size and non-symmetrical shape of the screw clamping mechanism make it difficult to maintain a tight impedance within the connector, resulting in attenuation of the signal at frequencies above 1 GHz to the detriment of the signal.
[0050] Figure 2 is a sectional view of part of a distribution outlet 10 ', or junction box, to show the connector 40 in accordance with the present invention. The connector 40 is located in the vicinity of the main ports 12, 20 and comprises a body 42 formed with channels 44, a torsion spring 46, and a metal post 48. The body 42 is normally made of insulating plastic material and acts as a insulated cap. Connector 40 is capable of receiving the main conductive pin from main connector 16 and establishing electrical contact between pin 26 and metal post 48, while post 48 in turn making electrical contact with a printed circuit board within the socket. 10 '.
[0052] Typically, the socket 10 'is integrally formed with an internal bracket 50 on which the connector 40 is mounted, the bracket 50 being substantially rectangular with an open central channel and cut-out portions 52 on which the body 42 sits. This ensures that the channels 44 are located at a height corresponding to which a connector pin will be inserted into the main input / output ports 12, 20. Above the body 42 is a printed circuit board terminal housing 54 within which There is a printed circuit board grounding spring 56, which is attached to bracket 50 by fasteners through two diagonally spaced openings 58, only one of which is visible.
[0053] Figure 3 (a) shows the connector 40 before its placement in the socket 10 'and Figure 3 (b) shows an exploded view of the parts that make up the connector 40.
[0055] Body 42 consists of upper and lower sections 60, 62, each of which is formed by a central cylindrical section 64 and four arms 66 equidistant circumferentially spaced that depend on section 64 to give a substantially shaped body 42. cross. Each of the upper and lower sections 60, 62 is formed by four slots 68, 68 ', 68 "and 68'", see Figure 4, which are directed inward from an outermost edge of each arm 66 to form a cross shape. At the intersection of the arms 66 there is provided a central opening 70 to receive the terminal metal post 48, with the metal post 48 formed with two intersection channels 72,74 to provide four connection openings to receive the plug 26.
[0057] As can be seen in Figures 3 (a) and 4, the grooves 68, 68 ', 68 "and 68'" are radially misaligned with respect to the arms 66, so that the entrance to the channel 44 is offset from the center of each arm 66 for each of the slots. The slots 68, 68 "'taper into the opening 70, with the side walls positioned at slightly different angles to provide taper in combination with deflection. In the case of slots 68' and 68", misalignment Radial is achieved by angled constant width grooves within the arm. If desired, each section 60, 62 could have two grooves arranged at 90 ° to each other instead of four grooves. This would produce an L-shaped channel with the inflection of the L located at the opening 70, ensuring that the connector 40 would be able to accommodate two orthogonally arranged connection points, such as the main ports 12, 20.
[0059] The two sections 60, 62 are substantially identical albeit with complementary fasteners 76 to allow them to be connected to each other using a soft-fit connection. The upper body 60 has a curved seat 78 associated with each arm 66 to aid in the positioning of the torsion spring 46.
[0061] Torsion spring 46 comprises a substantially rectangular central section 80 with a spring element 82 at each corner, comprising a downward curved edge 86 and a downward straight edge 88. Torsion spring 46 is configured in a shape complementary to that of the torsion spring. body 42, such that center section 80 sits on top section 60 and spring elements 82 are positioned and secured in the gaps between adjacent arms 66. Locating holes 90 and screw holes 92 are formed in spring 46 to ensure that spring 46 can be attached to a bracket or other structure.
[0062] During assembly of connector 40, post 48 is located within central opening 70 of each body section 60, 62 and body sections 60, 62 are engaged together using mating fasteners 76 to secure post 48 in position. , as seen in Figure 3 (a). The four spring elements of the spring 46 are then snapped into position between the arms 66 of the body 42 and two locating holes 90 and two radially positioned screw holes 92 such that, when assembled to the housing 22, the axis of each connecting channel or transverse hole of post 48 is held under spring pressure in misalignment with the insertion axis of inlet / outlet port 94, see FIG. 4.
[0064] After assembling the terminal post assembly consisting of the body sections 60, 62, the post 48 and the torsion spring 46, the terminal housing of PCB 54 with the grounding spring of PCB 56 is inserted into the holes position 90 of torsion spring 46. Next, connector 40 is inserted into bracket 50 and screwed into position, as shown in Figure 2, so that connector 40 is restrained vertically, but the body 42 can rotate about the vertical axis of post 48 within the constraints of the housing slots 52 and the force of torsion spring 46. An insulating guide bushing 96 made of plastic material is inserted into the main port 22 to limit the Radial movement of the conductive pin 26 as it is inserted along the insertion axis 94. If desired, the bushing 96 can be incorporated into the connector 40.
[0066] Figures 4-6 illustrate connector 40 in use. Terminal plug 38, which could alternatively be a socket, is rigidly mounted to body 42 which is mounted to housing 22 in a manner that allows limited radial movement. The torsion spring 46 acting on the body 42 establishes the first parking position of the plug of the terminal or socket 48 such that the axis of the connecting channels 72, 74 in the terminal 48 are radially misaligned with the axis of the terminal. main port 12 in housing 22.
[0068] As main connector 16 'is inserted into main port 12, a guide bushing 96 in housing 22 directs the center pin of conductor 26 of connector 16' along insertion axis 94 toward terminal 48.
[0070] As the conductive pin 26 is pushed into the channel 44, see Figure 4, the channel 44 guides the plug 26 towards the connecting channels 72, 74 in the terminal 48. It can be seen that the insertion shaft 94 and the channel axis 98 are not aligned and are offset from each other.
[0071] As lead plug 26 continues to be driven / forced into guide channel 44, see Figure 5, the terminal post assembly consisting of upper and lower sections 60, 62 and terminal 48 rotates radially against the force applied by torsion spring 46. The terminal post assembly continues to rotate against the force of torsion spring until insertion axis 94 and channel axis 98 are aligned and conductive pin 26 is able to enter connecting channel 74 and extending just beyond terminal 48, see Figure 6. When in this aligned position, arms 66 have been rotated to be disposed closer to one side of their respective housing slot 52.
[0073] The biasing force of torsion spring 46 acts to resist withdrawal of pin 26 once inserted, thereby ensuring that pin 26 is retained without the need for additional attachment of pin 26 to post 48.
[0075] This construction of connector 40 eliminates the need to manually screw in the mating conductor and its associated plug. All metal components are small and symmetrical in shape, allowing tight control of the connector's characteristic impedance and achieving operating frequencies of up to 3 GHz or higher. Furthermore, the constant radial force on the center contacts and the large contact surface result in low contact resistance. This allows large currents of up to 15A to pass through without causing the connector to heat up significantly.
[0077] The design of the mechanical connectors for the input and output of the main cable line is an important factor in matching the impedance of the junction box to that of the network to allow efficient signal transmission.
